Carbonda 505SL Integrated Stem

[jakonodi]

Hello, I am going for the new 505 SL. I ordered the non-integrated version which would take a little bit longer to deliver. So I decided to swap to the integrated version. Has anyone experience which integrated stem would fit? I prefer to have handlebar and stem separat for easier maintenance. Thank you for suggestions.

I would check the headset spec to make sure that it is 1.5 to 1.5, but my guess would be that they are using the ACR spec. In which case any semi-integrated stem should work. There are a few from name brands as well as Chinese manufacturers.

Can you share any details you have about the 505 SL? Any images? Information is sparse and when I asked about it Adam basically said "yes, its a thing" without much else.

Katie sent this photo and wrote: "The headset size is 1-1/2"* 1-1/2”ACR". As soon as the frame arrives I can provide photos. Should be in Germany in 10-20 days.The one attached also came from Katie@Carbonda. Right now I prefer the Specialized SL7 stem, not sure if it fits and if I need something more like another headset. I am not building up myself, a friend does the job. But I want to have everything ready. Right now I have a Carbonda 696. Very good gravel bike, just made the mistake to buy a size too big. Like many others... So now I'll try the 505SL.

Yes it is 1.5"/1.5"
T47 BB is the first available
UDH hanger
They provide CGB02 an integrated handlebar, flared by 6cm on the 40cm wide.

I'm looking forward to get and see the two I ordered.
One will be a mullet Force/XX and maybe the second too

Hi Carbonazza, do you think the Specialized SL7 stem would fit? Do I need anything else? Headset?

You'll need a 1.5" dust cover

Ritchey is doing one :

This one looks promising, but I never tried :

Hello Carbonazza, the photo shows the included headset and what seems to be a dust cover. On top of that I need the Ritchey cover? Sorry for asking again will be my first integrated stem...

Ask them, but this is probably the dust cover that is just designed for their handlebar, not the SL7 stem.
In your case you need a more generic part, such the Ritchey one.

Where do you find info on this frame? I can't find it on the Carbonda website.

Seems to be their new frame. Just write to carbonda and ask for it. Geo almost similar to the classic 505 (not on their hp either but can be googled) https://www.carbonda.com/road/gravel/cfr505.html Small changes were made and it is 200 g lighter. Mine is in custom for almost 3 weeks now....

I received my CFR505-SL this week, building up with Shimano GRX810 2x11. I've never been disappointed by Carbonda, and pretty happy with the quality on this one. They did forget to include my seatpost clamp, fortunately have a spare in my parts box. Will post more pictures later.

I've built up many frames up over the years, this is the first using an integrated handlebar (the CGB02).

Differences between CFR505-SL and CFR505:

• Headset size: 1-1/2"* 1-1/2”ACR (two 40 x 52 x 7mm: 45x45 deg bearings)
• Rotor size: 160/180 mm
• The rear brake cable exit was changed to the same design as CFR707
• The front derailleur cable routing was changed to the same design as FM1056
• Seat tube was changed to normal seat tube clamp design, same as CFR696
• Removed rack and fender mounts. Only keep two sets of water bottle cage mounts. (My frame has 3 with the downtube mount)
• Max tire size:700x42c  / 650B*47c
• Max chainring: 50-34T / 42T
• T47 bottom bracket
• All mounts removed from fork. There are internal and external routing versions.

Build Notes:

• Rear caliper: flat mounts on the chain stay are 25mm thick, so if you're using Shimano calipers & SM-MA-R160D/D adapter, you will need 38mm long bolts (Shimano part Y8N208020)
• Headset bearings: Don't quite trust the quality of the supplied bearings, and considering what a PITA it will be to replace the them, I plan to order new Cane Creek or Enduro bearings for the build
• Front derailleur: cable uses housing from the shifter to to a plastic guide below the BB (pic attached). From there it's inner cable to the RD. You'll need around 1.4m of housing
• Rear derailleur: cable use housing from the shifter all the way back to the rear derailleur. I'm using a GRX810 RD, so I need to use the flexible Shimano OT-RS900 housing where the cable exits the frame to the RD. I'm using a Jagwire Double-Ended Housing Connector CHA062 to join the two cables. Note the Jagwire Pro cable kits (e.g. PCK500 ) also include the flexible cable section and double-ended connector.
• Get some Internal Housing Damper foam (6mm ID, 10mm OD) for the rear brake hose and shift cables to stop it rattling in the frame. I have some made by Jagwire (ZSK600), you'll need around 2-3m

Got my CFR505-SL built up yesterday with Shimano GRX810! Still waiting for my wheel parts, so using a spare wheelset with 32mm tires until they arrive.

Did the inaugural ride ride today which was cut short by a slipping seatpost . Carbonda forgot to include my seatpost clamp but immediately sent me one, which is in the mail. I'm using an old spare clamp I had, but it has never gripped well, even if the seatpost is slathered in carbon paste.

First impressions are that the bike is very comfortable, absorbs a lot of vibration from the road. I ordered the 420x90mm integrated handlebar, and I have to say the top is kinda narrow. I would say get at least a 20mm wider bar that your normal bar width. The drops are wide and very comfortable.

@dogsbollocks what size is that?

[DogsBollocks]

It's a large - 564.1mm top tube, 594.6mm stack & 388mm reach

@dogsbollocks what size is that?

Hi, my 505SL arrived after 5 weeks in customs... Already build up, looks great! Only problem so far I choose FSA ACR headset, seems to work. I go for semi integrated to be flexible.
Which semi integrated stem will work with FSA? Right now I mounted a Specialized SL7 stem but the spacers do not fit...looks weird.
